Medela Harmony Flex Membrane (diaphragm)

Replacement Harmony Flex Membrane

This spare part is for the replacement of a worn, damaged or lost/missing diaphragm for the Medela Harmony Flex breast pump.

This piece is also referred to as a 'diaphragm/stem with O-ring'.

The stem (with the O-ring) is inserted into the hole on the upper side of the diaphragm - the stem and the diaphragm are part of the Harmony pump's handle.
